摘要:
York University The four articles in this special issue of Human Computer Interaction describe recent research in mobile text entry. Text entry research is by no means new. We can depict the progression of text entry research as occurring in two waves. The first was in the 1970s and early 1980s in response to the new role of electronic computers in automating office tasks, such as typing, word process- ing, and document management. Modeling 10-finger touch typing, categoriz- ing typing errors, task analysis, and comparing document editing strategies are some of the themes in this early research. Exemplary references are Cooper (1983) and Chapters 3 to 9 in The Psychology of Human Computer Interaction (Card, Moran, & Newell, 1983). The second wave of text entry research was not aimed at two-handed input in the workstation setting but at the more demanding environment of mobile computing. This began with the arrival of pen-based systems in the early 1990s. The automated recognition of handwritten text entered with a stylus was the elixir for this new mode of interaction, it seemed. Although the poten- tial of pen-based computing, and mobility in general, was well beyond the rec- ognition of hand-printed symbols, this aspect of the interaction received much of the attention. And the attention was not good. Promises did not meet the ex- pectations of demanding users, and the market suffered significantly for this. Yet products continued to arrive. The single most significant event in pen-based computing was the introduction in 1995, and tremendous success of, the Palm Pilot from Palm, Inc. (now a division of 3Com). For text entry, Palm sidestepped many of the problems with existing handwriting recogni- tion technology. To avoid the segmentation problems inherent in multistroke
